You are running 12, and it is now at 16. If there is no package for your system the source archive for 16 is located at ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.16.tar.bz2. And here is a link to the latest snapshots for all of the alsa archives. Because they have converted to git, you will have to follow the link inside the readme to get the actual archive. ftp://ftp.suse.com/pub/projects/alsa/snapshot/ Second, download and run the script at this location http://hg.alsa-project.org/alsa/raw-file/tip/alsa-info.sh and then post back the link so that people can see your sound setup? The script scans your machine and extracts out things relevant for diagnosis and puts them on a website. It gives you a link to the information that you can post here. If these give you no joy, then it is time to troubleshoot. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
